SPECIFICATION forming part of Letters Patent No. 358,515, dated March 1, 18%?.

Application lcd May 24, 1886. Serial No. 203,134. (No model.)

To all whom, it may concern.-

Be it known that I, FREDERICK WEs'rna BECK, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Machines for Soldering Cans, of whichthefollowingis a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure 1 is a top view ofthe machine. Fig. 2 is a vertical section at 2 2, Fig. l. Fig. 3 is a horizontalsection at 33, Fig. 2. Figui is a detail showing the position of the can in the acid-trough, the trough being in section. Fig. 5 is a detail showing the position of the can in the soldering-trough, which latter is shown in section. Fig. 6 shows the can when lifted from the soldering-trough and about to be discharged. Fig. 7 is a side View of the cam by which the can-clamping arm is lifted. Figs. 8 and 9 are, respectively, detail top and side views showing a modification. Fig. 10 shows a modification. Fig. ll is an enlarged side view of the outer end of the lever, partly in section, showing the upper disk in elevation.

In this machine the cans are clamped to spindles on a rotating head, one of the corners of each of the cans being tirst dipped or immersed in a trough containing acid and then in a trough containing melted solder.

A is the frame.

A is the drive-shaftjournaled in the frame, having a worm-gear, B, engaging a wormwheel, C, on the vertical shaft D. The shaft D turns in bearings, respectively, in arm E of the frame and the block F, supported on the frame. Upon the shaft is fixed a rotating head, G, having radial arms H, formed with inner bearings, I, for the shafts J. Each shaft .I carries a spur-Wheel or pinion, K, and a bevel-wheel, L. The pinion K engages with the teeth or cogs of a circular rack or masterwheel, M, fixed immovably to the block F of the frame of the machine, so that as the head G rotates the shafts J will be caused to rotate also. The bevelwhcel Lengages with a bevelwheel, N, splned upon a spindle, O, which turns in outer bearings, l? and P', upon the arm H. The construction is such that the spindle has endwise motion through the bevelwheel N,while the spindle turns with the bevelwheel and the bevel-wheel is restrained from endwise motion by bearing against the bearings P and P above and below. The spindle carries at its upper cud a disk, Q. iiXed thereto, upon which the lower end of the can R rests.

S are standards,extending obliquely upward and outward from each ofthe arms H, and each carrying an arm, T, to which is fulcrumed a lever, U. The lever U works in a guideslot, s, of the standard S, within which is a spring. V, one end of which is attached to the standard and the other end to the lever. The office of the spring Visto draw down the free end of the'lever and hold the can in place. For this purpose the free end ot' thelever can ries a disk,` W, which is connected therewith by a ballandsocket joint, w, so as to turn with the can. The form of this joint which I have used is shown by section in Fig. 11. I do not, however, conline myself to any particular form of ball-and-socketjoint. Ajoint of this character is needed to allow the disk to turn with the can and to adjust itself to cans of different lengths, and also to allow the can to be moved upward, in jumping the ends of the troughs, without interfering with the fiat bearing of the disk XV upon the end of the can. The lever has ahandle, U', by which it can be lifted. Its downward movement may be limited by a pin, s, or other means.

X and Y are two troughs forming together a part of a circle concentric with the shaft D. The cans are first carried with their lower corners, r, through the trough X, containing acid, sometimes, also, some textile material which is saturated with the acid, and which serves to apply it to the joint between the end R and side R2 of the can. The can pierforms at least one rotation with the spindle as an axis while passing through the trough X. The trough Y contains melted solder, `in which the lower corner, r, is immersed. lt is preferred that the spindle O should make two rotations while the can is passing over the solder-trough, so as to assure a perfect joint. At the ends Y ofthe solder-trough the` can is raised by mechanism, which will be now described. The end O of the spindle O projects below the lower bearing, P', and, as the can is about to reach the end Y' of the trough, this IOO VIo

end O comes in contact with the periphery of one of tWo wheels, Z, and the spindle, with the can, is pushed upward bythe wheel, and the corner r of the can lifted above the end of the trough. (See Fig. 6.) The solder-trough is supported on screw-legs Y2, fitting in holes made 1n the arms a ofothe frame, said legs having nutsYarestingon thearms. Thetrough is made adjustable to suit cans of different diameters.

Y is a cover, chiefly to prevent the oxidatlon of the solder, and also to keep dust from enterlng'the trough and stay the cooling of the solder. An opening or slot, Y5, receives the corner of the can. The cover is not iu any way intended to support or form a guide for the cans, which, during their solder bath, rest on their bearings P, and the solder-trough being vertically adjustable on its screw-legs Y2, the depth of the diprequired is thus regulated independent of any track. The passing of the cans through their bath without running on any track (which latter causes vibratory movement) is an important feature, besldesavoiding the rough marginal outline of the soldering that even the smoothest track unavoidably engender-s.

b are gas-jets or other burners by which the trough is heated and the solder is melted. The solder is fed into the trough by means of the holes c, a stick of solder being placed in each hole, which descends as its lower end melts. This cover Y'1 should be made removable, so that it mav be changed, when desired,

to suit a can of different diameter.

When the cans have reached the last end of the solder-trough and have been raised over it, the handle U of the lever U comes in contact with the lifting-cam d, and, as the lower end O of the spindle O passes up and over the wheel Zand the can descends, the disk W is held up by the cam d and the can falls out from between the disks Q and W, and another can is placed between them by the operator.

In the modications shown in Figs. 8 and 9 the standard S, in place of being over the can, 1s at oneside of the same, so that the cans may be introduced from above. The handle U projects radially, as in the other form, so as to come in contact with the cam d.

ln Fig. 10 two adjustable arms, e, are shown attached to the standard S, the arms carrying guide-rollers e', against which the sides of the can are placed in putting itin position. These arms e are made adjustable at the connection e2, the arms having slots e3, through which pass the connection-bolts e".

I claim as my invention- 1. The combination of the rotating head provided with bearings, the stationary masterwheel, spindles turning in the bearings having disks xed thereto for supporting the cans to be soldered, gearing connecting the spindles to the stationary master-wheel, standards secured to the arms, and'upper disks supported by the standards for clamping the cans to their seats and rotating with the cans, substantially as described.
